ro @ZZ 'whom it may concern:

Be it known that l, FoRREsTE. CARDULLO, a citizen oi' the United States, and ai r'esident oi Cincinnati, in the county of Hamilton and State of Ohio, have invented certain a metal planer and tocollect this oil, after.

use, and purify it for furtheruse, ln this connection l provide for a special construe'- tion of planer bed and table V., which permits the distribution. pf oil under controlled and practically uniform pressure to all parts of the sliding'surfaces. oil pressure system which is readily accessible for adjustment and assembly, and. in which the ilter parts may be quickly and e'ectively cleaned.

'llhese objects and other advantages to be noted l accomplish by that certain construction and arrangement of parts to'be hereinafter more specifically pointed out and claimed.

l also provide an Figure I is a longitudinal section through the end of the planer bed, taken on the line 7-7 of Figure 8 and showing the oil receiving trough and screen. r

.Figure 8 is a cross section taken at the end of the bed on the line 8 8- of F ignre 7, showing the same parts as in Figure 7.

rlhe bed of the vplaner is indicated'in the various views as l. Bolted or otherwise fastened to this bed or trame (Figure l) is a casting 2,-which forms a support for pump 3. Pump 3 may be of any lsuitable type, but I ll prefer to use a gear pumpprovided with check valves, 'so that the gears may be caused to revolve in either direction without changing the direction of flow ofthe fluid. Pump 3 is provided Nwith gear 4 which meshes with gear 5 fastened to shaft 6, or, if preferred, may be driven directly from shaft 6, or by an independent source of power. Sha-ft 6 is the pulley or motor'shait which drives the planen The planer is provided with two or i yOre other shafts 7-77 carrying gears "which serve to drive the table.

voir 1.5, preferably cylindrical in form,

Jformed in casting 2, or in some suitable part of the planer bed or housings. rllhis reser- Voir is lled with clotlnlwool or other suitable ltering material 15a. This reservoir is closed by cap i6- which is held down ley two or more suitable screws.

From this reservoir extend ipes 8 provided with Ts or other suitab e fittings 9 from which extend pipes lll-@llfll and 17.

Pipe 17 is provided with a suitable relief valve to be describedlater. Pipes ll-ll-ll lead to the ditlerentjjbearings for shafts 6 and 7--7-7, supplying them with cil. Pipes 8 also discharge into connections 10,

which communicate 'with drilled holes i8 way that it communicates with hole' 18.

drilled into the ways of the bed, so that oilA u) in wie Ways of the bed is trible provided oil s under side with Ws i9 which sceuret ljy litthe ways in 'the bed. i

Referring now to Figure 3. llt will be seen that the il of the 'table isV oil two different sections us illustrated in Figure 5 und Figure 6. From point 25 to point, the teiole if has the sections shownA in Figure 5, end fits Very closely the Way of the planer. l? rom point 26 to point 27., the table l! hes the sectionshown in Figure 6; the point of the if being cut sway et 19". From point 27 to iut 28, the u is agein of the section which tits the Way From point 2o 'to point 2'? there therefore extends s trough of trianguler section, bounded on two sides by portions oit the Way und onthe third side hy the lf? und closed et either end. rlfhis trough is connected with 'the-oil supply by drilled hole `oep 37 which. slides eesiiy upon tube l@ snol is capable of carrying oil to points :26 `und 27.

@n the surface of the planer il' are out oil grooves 29 and 30 which can be of enysuitsbl-e form, but which il prefer to Ineke oft the zigzag form shown. rlhe groove neer the top et the V et the end is cut through to the of the table, :is :it point 313 but the groove et the bottom near the end is not out through, es et point I39.

The cross section or the grooves 29 und 30 is only-sJ very smell traction of the cross section of the triangular trough, consequently While oilwill how out through 'the grooves 'to the end -oi the table, the pressure of the oil he'tween point 26 end point 27 will loe practically uniform eren though the table be in such u, position that opening i8 isnesr ypoint 26 or 2'?. Because or the relatively smell eres and hydraulic redius or the oil grooves, the loss in pressure in flowing `from point 26 to point 3l is much greater than the loss in pressure of the oil owing ntrono point 27 to point 26. The itlorv of oilthrough the grooves et either end of the table is therefor substantially eepisi,` whatever the position of the tehle with reference to hole 18.

lin order to maintain the oil et the proper pressure, l :ritiri to pipe 1.7 a, pressure relief Lfe-ive 33 shownin section in Figure This consists of e pipe or tube 34 threaded at one end et 35 und having drilled in it e number of holes 36. @Ver it is slipped the hollow llhe pressure of the oil in tube Se rsises the esp 37 so that the oil escapes through holes 36, end drains beck into resewoirv l2. Any increase in pressure over that required to -liitt the'cep 37 above the holes results in s greater flow of oil which relieves this pressure so that the pressure is maintained et en ereount which depends pinto the end of upon of oep 3/ une i'ioop. however the 'ci from the puin i eoues less thun the ow olf' eii io the ings, @up 37 will descend u short 'tence by its own ahead of it und ur". the pressure constant, since7 in the position :uiounthc oil cannot escupe throutgh hole 36. lhe gncssure regulating veire 33 thus uets also us :in accumulator7 which sends ruisntity of oil into the system und inuintuius the oil pressure constant duringthe reversal or 'the planer When. the discharge or the pump ceases for en instemto instead of providing seperate pipes? :is il, leading from pipe 8 to the o i rent hcurinfgs in order to lubricste the i Y i j holes een be drilled from the bottoni of ilio Ways into the beuri Us; such, :i holo boingshown as 2.3 und rin mure ln this use, the nipple @supplies oii to the holo l iu exuctlythe sume ni.

is usuel to permit the table in u planer to extend three or four leet beyond the end of the bed when i't'is in either extremo posi tion. f lhis is objectionable `for the reurou that the overhingingn weight ot' the table eauses it to spring slightly which in iuru causes the table to heur heziviljy .it the oud of the bed. This Wears the wsys :it the end oi the bed` und Wears the table fi/ls :it s. point from two und one-half to three und one-hui l: :feet back 'from the end. ln order to smid this injurious action and to provide sut' fue tory oiling when the tubleis :it the er; 'eiuo end of its stroke, l extend the bed so that he table does not et sny finie overhung the end of the bed.

Ulli

nemers Grit and other heavy material contained in the oil will settle to thebottornof reservoir 38, whence it may readily be removed. The horizontal area of reservoir 38 is such that the velocity ot dow Voit the oil through-the .reservoir is very low, permitting complete n sedimentation et grit, chips and so on. ln addition, the top of this reservoir is coveredl by steel plate 4:8 through which-a number of small holes aredrilled so that the oil can descend intoQ reservoir 38 Without carrying with it large particles.

When the table is in its extremeposition, its end coincides with dotted line 4:9 so that any oil which drips trom the Vs, the rack, or'the`4 under side of the table, will fall upon -the plate 458er the web 39, and drain thence intoreservoir 38, to be returned by pipe 4:4 to reservoir 12. The distance between points 25 and 26,y and points 27 and 28, is

made such that as soon-as the end of the.

table reaches point 51, pointA 27 slides over and covers oil passage 18, so that trough 25 is no longer connected Withthe source of oil pressure. Consequently when the table projects over the end of the Vs in the position shownin Figure 7, oil is not forced through the oil grooving, although 'during this time the grooves remain filled with the oil and lubricate .the surfaces over which they slide.

By reference to but one set of specific mechanisms in theabove specification l do not Wish to limit myself to the details' described, but desire to include Within the range oi my invention all the usual equivalent structures in the art involved.

Having thus described-my' invention, what lv claim as new and desire to secure by Letters Patent, is
